BACKGROUND OF THE INVENTION

Gram-negative bacteria are intrinsically resistant to many small molecules owing to the presence of an outer membrane, which acts as a permeability barrier. tRNA synthetases are involved in protein biosynthesis so that inhibition thereof may be expected to lead to a cessation of cell growth. Thus, for instance, the compound mupirocin, produced by the organism Pseudomonas fluorescens, is an antibacterial agent and is used as the active ingredient in the product Bactroban, marketed by GlaxoSmithKline. However, mupirocin is only effective against Gram-positive, but not Gram-negative bacteria. Mupirocin has been shown to be an inhibitor of the isoleucyl tRNA synthetase. Each tRNA synthetase represents a separate target for drug discovery. tRNA synthetase inhibitors which are selective for bacterial cells over mammalian cells are of considerable therapeutic interest as they have the potential to be used as antibacterial agents. Thus, there remains a need to develop compounds having inhibitory activity toward tRNA synthetase in Gram-negative bacteria.

DETAILED DESCRIPTION OF THE INVENTION

The present invention is based on the discovery of a class of compounds with surprising antibacterial activity. A description of example embodiments of the invention follows.

Definitions

“Alkyl” means an optionally substituted saturated aliphatic branched or straight-chain monovalent hydrocarbon radical having the specified number of carbon atoms. Thus, “(C₁-C₆) alkyl” means a radical having from 1-6 carbon atoms in a linear or branched arrangement. “(C₁-C₆)alkyl” includes methyl, ethyl, propyl, butyl, pentyl and hexyl.

“Alkylene” means an optionally substituted saturated aliphatic branched or straight-chain divalent hydrocarbon radical having the specified number of carbon atoms.

Thus, “(C₁-C₆)alkylene” includes a divalent saturated aliphatic radical having from 1-6 carbon atoms in a linear arrangement, e.g., —[(CH₂)_(n)]—, where n is an integer from 1 to 6, “(C₁-C₆)alkylene” includes methylene, ethylene, propylene, butylene, pentylene and hexylene. “(C₁-C₆)alkylene” also includes a divalent saturated radical having from 1-6 carbon atoms in a branched arrangement, for example: —[(CH₂CH₂CH₂CH₂CH(CH₃)]—, —[(CH₂CH₂CH₂CH₂C(CH₃)₂]—, —[(CH₂C(CH₃)₂CH(CH₃))]—, and the like. Where indicated, alkylene is optionally and independently substituted with one or more substituents independently selected from halo, (C₁-C₆)alkyl, —OH, ═O, (C₁-C₆)alkoxy, and (C₁-C₆)haloalkyl.

“Aryl” or “aromatic” means an aromatic monocyclic or polycyclic (e.g. bicyclic or tricyclic) carbocyclic ring system. In one embodiment, “aryl” is a 6-12 membered monocylic or bicyclic system.

TABLE 1 Compounds of the Invention

Further compounds of the invention include, but are not limited to the following compounds in Table 2. IDC-329 TRE M

TABLE 2

Pharmaceutical Compositions

In certain aspects, the invention also provides a pharmaceutical composition comprising a compound of the invention (e.g., a compound of formula (I)), in combination with a pharmaceutically acceptable carrier.

The invention further includes the process for making the composition comprising mixing one or more of the present compounds and an optional pharmaceutically acceptable carrier; and includes those compositions resulting from such a process, which process includes conventional pharmaceutical techniques.

The compositions of the invention include ocular, oral, nasal, transdermal, topical with or without occlusion, intravenous (both bolus and infusion), inhalable, and injection (intraperitoneally, subcutaneously, intramuscularly, intralesionally, or parenterally) formulations. The composition may be in a dosage unit such as a tablet, pill, capsule, powder, granule, liposome, ion exchange resin, sterile ocular solution, or ocular delivery device (such as a contact lens and the like facilitating immediate release, timed release, or sustained release), parenteral solution or suspension, metered aerosol or liquid spray, drop, ampoule, auto-injector device, or suppository; for administration ocularly, orally, intranasally, sublingually, parenterally, or rectally, or by inhalation or insufflation.

Compositions of the invention suitable for oral administration include solid forms such as pills, tablets, caplets, capsules (each including immediate release, timed release, and sustained release formulations), granules and powders; and, liquid forms such as solutions, syrups, elixirs, emulsions, and suspensions. Forms useful for ocular administration include sterile solutions or ocular delivery devices. Forms useful for parenteral administration include sterile solutions, emulsions, and suspensions.

The compositions of the invention may be administered in a form suitable for once-weekly or once-monthly administration. For example, an insoluble salt of the active compound may be adapted to provide a depot preparation for intramuscular injection (e.g., a decanoate salt) or to provide a solution for ophthalmic administration.

The dosage form containing the composition of the invention contains an effective amount of the active ingredient necessary to provide a therapeutic effect. The composition may contain from about 5,000 mg to about 0.5 mg (preferably, from about 1,000 mg to about 0.5 mg) of a compound of the invention or salt form thereof and may be constituted into any form suitable for the selected mode of administration. The composition may be administered about 1 to about 5 times per day. Daily administration or post-periodic dosing may be employed.

For oral administration, the composition is preferably in the form of a tablet or capsule containing, e.g., 500 to 0.5 milligrams of the active compound. Dosages will vary depending on factors associated with the particular patient being treated (e.g., age, weight, diet, and time of administration), the severity of the condition being treated, the compound being employed, the mode of administration, and the strength of the preparation.

The oral composition is preferably formulated as a homogeneous composition, wherein the active ingredient is dispersed evenly throughout the mixture, which may be readily subdivided into dosage units containing equal amounts of a compound of the invention. Preferably, the compositions are prepared by mixing a compound of the invention (or pharmaceutically acceptable salt thereof) with one or more optionally present pharmaceutical carriers (such as a starch, sugar, diluent, granulating agent, lubricant, glidant, binding agent, and disintegrating agent), one or more optionally present inert pharmaceutical excipients (such as water, glycols, oils, alcohols, flavoring agents, preservatives, coloring agents, and syrup), one or more optionally present conventional tableting ingredients (such as corn starch, lactose, sucrose, sorbitol, talc, stearic acid, magnesium stearate, dicalcium phosphate, and any of a variety of gums), and an optional diluent (such as water).

Binder agents include starch, gelatin, natural sugars (e.g., glucose and beta-lactose), corn sweeteners and natural and synthetic gums (e.g., acacia and tragacanth). Disintegrating agents include starch, methyl cellulose, agar, and bentonite.

Tablets and capsules represent an advantageous oral dosage unit form. Tablets may be sugarcoated or film-coated using standard techniques. Tablets may also be coated or otherwise compounded to provide a prolonged, control-release therapeutic effect. The dosage form may comprise an inner dosage and an outer dosage component, wherein the outer component is in the form of an envelope over the inner component. The two components may further be separated by a layer which resists disintegration in the stomach (such as an enteric layer) and permits the inner component to pass intact into the duodenum or a layer which delays or sustains release. A variety of enteric and non-enteric layer or coating materials (such as polymeric acids, shellacs, acetyl alcohol, and cellulose acetate or combinations thereof) may be used.

Compounds of the invention may also be administered via a slow release composition; wherein the composition includes a compound of the invention and a biodegradable slow release carrier (e.g., a polymeric carrier) or a pharmaceutically acceptable non-biodegradable slow release carrier (e.g., an ion exchange carrier).

Biodegradable and non-biodegradable slow release carriers are well known in the art. Biodegradable carriers are used to form particles or matrices which retain an active agent(s) and which slowly degrade/dissolve in a suitable environment (e.g., aqueous, acidic, basic and the like) to release the agent. Such particles degrade/dissolve in body fluids to release the active compound(s) therein. The particles are preferably nanoparticles or nanoemulsions (e.g., in the range of about 1 to 500 nm in diameter, preferably about 50-200 nm in diameter, and most preferably about 100 nm in diameter). In a process for preparing a slow release composition, a slow release carrier and a compound of the invention are first dissolved or dispersed in an organic solvent. The resulting mixture is added into an aqueous solution containing an optional surface-active agent(s) to produce an emulsion. The organic solvent is then evaporated from the emulsion to provide a colloidal suspension of particles containing the slow release carrier and the compound of the invention.

The compounds disclosed herein may be incorporated for administration orally or by injection in a liquid form such as aqueous solutions, suitably flavored syrups, aqueous or oil suspensions, flavored emulsions with edible oils such as cottonseed oil, sesame oil, coconut oil or peanut oil and the like, or in elixirs or similar pharmaceutical vehicles.

Suitable dispersing or suspending agents for aqueous suspensions, include synthetic and natural gums such as tragacanth, acacia, alginate, dextran, sodium carboxymethylcellulose, methylcellulose, polyvinyl-pyrrolidone, and gelatin. The liquid forms in suitably flavored suspending or dispersing agents may also include synthetic and natural gums. For parenteral administration, sterile suspensions and solutions are desired. Isotonic preparations, which generally contain suitable preservatives, are employed when intravenous administration is desired.

The compounds may be administered parenterally via injection. A parenteral formulation may consist of the active ingredient dissolved in or mixed with an appropriate inert liquid carrier. Acceptable liquid carriers usually comprise aqueous solvents and other optional ingredients for aiding solubility or preservation. Such aqueous solvents include sterile water, Ringer's solution, or an isotonic aqueous saline solution. Other optional ingredients include vegetable oils (such as peanut oil, cottonseed oil, and sesame oil), and organic solvents (such as solketal, glycerol, and formyl). A sterile, non-volatile oil may be employed as a solvent or suspending agent. The parenteral formulation is prepared by dissolving or suspending the active ingredient in the liquid carrier whereby the final dosage unit contains from 0.005 to 10% by weight of the active ingredient. Other additives include preservatives, isotonizers, solubilizers, stabilizers, and pain-soothing agents. Injectable suspensions may also be prepared, in which case appropriate liquid carriers, suspending agents and the like may be employed.

Compounds of the invention may be administered intranasally using a suitable intranasal vehicle.

In other embodiments, the compounds of this invention may be administered directly to the lungs by inhalation.

Compounds of the invention may also be administered topically or enhanced by using a suitable topical transdermal vehicle or a transdermal patch.

For ocular administration, the composition is preferably in the form of an ophthalmic composition. The ophthalmic compositions are preferably formulated as eye-drop formulations and filled in appropriate containers to facilitate administration to the eye, for example a dropper fitted with a suitable pipette. Preferably, the compositions are sterile and aqueous based, using purified water. In addition to the compound of the invention, an ophthalmic composition may contain one or more of: a) a surfactant such as a polyoxyethylene fatty acid ester; b) a thickening agents such as cellulose, cellulose derivatives, carboxyvinyl polymers, polyvinyl polymers, and polyvinylpyrrolidones, typically at a concentration n the range of about 0.05 to about 5.0% (wt/vol); c) (as an alternative to or in addition to storing the composition in a container containing nitrogen and optionally including a free oxygen absorber such as Fe), an anti-oxidant such as butylated hydroxyanisol, ascorbic acid, sodium thiosulfate, or butylated hydroxytoluene at a concentration of about 0.00005 to about 0.1% (wt/vol); d) ethanol at a concentration of about 0.01 to 0.5% (wt/vol); and e) other excipients such as an isotonic agent, buffer, preservative, and/or pH-controlling agent. The pH of the ophthalmic composition is desirably within the range of 4 to 8.

In certain embodiments, the pharmaceutical composition of the invention further comprises one or more additional agents, such as a second antibacterial agent. The other agent may be ay agent that is capable of treating, suppressing, or preventing a bacterial infection. For example, the other therapeutic agent may be an antibacterial compound.

Alternatively, the other therapeutic agent may be any agent of benefit to a patient when administered in combination with the tRNA synthetase inhibitor compound in this invention.

In certain embodiments, the second antibacterial agent in the pharmaceutical composition of the invention is a tRNA synthetase inhibitor. Exemplary tRNA synthetase inhibitors include oxaborole compounds such as AN3365.

Example 7: General Compound Syntheses 7

Step A:

A solution of 2-hydroxybenzaldehyde 1 (5.0 mmol, 1.0 equiv), K₂CO₃ (7.5 mmol, 1.5 equiv), compound 2 (5.0 mmol, 1.0 equiv) in CH₃CN (50 mL) was refluxed and monitored by TLC. After completion of the reaction, the solution was cooled; solvent was evaporated under reduced pressure. The residue was poured into water (30 mL) and extracted with ethyl acetate (3×30 mL). The organic layer was washed with brine and dried over anhydrous MgSO₄. Filtration of MgSO₄ and evaporation of solvent under vacuum gave the crude product. The residue obtained was purified by using HPLC to obtain the corresponding compound 3. Yield: 34-58%.

Step B:

Aldehyde 3 (0.55 mmol), amine 4 (0.5 mmol) were dissolved in 0.6 ml MeOH, heated at 100° C. for 2 hours, then mixture was cooled, NaBH₄ (0.5 mmol) was added and stirred for 4 hours. The mixture was heated for 2 hours at 60° C., 3 ml of methanol and 0.2 g of C-18 chromatographic phase were added, stirred for 2 hours, filtered, evaporated and optionally dissolved in 0.5 mL of DMSO. The residue was purified using HPLC. Yield: 24-47%.

Example 8: General Compound Syntheses 8

General Procedure for Preparation of Target Compounds 5: Step A:

The solution of 2-hydroxybenzaldehyde 1 (5.0 mmol, 1.0 equiv), K₂CO₃ (7.5 mmol, 1.5 equiv), compound 2 (5.0 mmol, 1.0 equiv) in CH₃CN (50 mL) was refluxed and monitored by TLC. After completion of the reaction, the solution was cooled; solvent was evaporated under reduced pressure. The residue was poured into water (30 mL) and extracted with ethyl acetate (3×30 mL). The organic layer was washed with brine and dried over anhydrous MgSO₄. Filtration of MgSO₄ and evaporation of solvent under vacuum gave the crude product. The residue obtained was purified by using HPLC to obtain the corresponding compound 3. Yield: 32-53%.

Step B:

Aldehyde 3 (0.55 mmol), amine 4 (0.5 mmol) were dissolved in 0.6 ml MeOH, heated at 100° C. for 2 hours, then mixture was cooled, NaBH₄ (0.5 mmol) was added and stirred for 4 hours. The mixture was heated for 2 hours at 60° C., 3 ml of methanol and 0.2 g of C-18 chromatographic phase were added, stirred for 2 hours, filtered, evaporated and dissolved in 0.5 ml of DMSO, and purified using HPLC. Yield: 24-47%.

Example 9: General Compound Syntheses 9

Step A:

A solution of 2-hydroxybenzaldehyde 1 (5.0 mmol, 1.0 equiv), K₂CO₃ (7.5 mmol, 1.5 equiv), compound 2 (5.0 mmol, 1.0 equiv) in CH₃CN (50 mL) was refluxed and monitored by TLC. After completion of the reaction, the solution was cooled; solvent was evaporated under reduced pressure. The residue was poured into water (30 mL) and extracted with ethyl acetate (3×30 mL). The organic layer was washed with brine and dried over anhydrous MgSO₄. Filtration of MgSO₄ and evaporation of solvent under vacuum gave the crude product. The residue obtained was purified by using HPLC to obtain the corresponding compound 3. Yield: 29-53%.

Step B:

Aldehyde 3 (0.55 mmol), amine 4 (0.5 mmol) were dissolved in 0.6 ml MeOH, heated at 100° C. for 2 hours, then mixture was cooled, NaBH₄ (0.5 mmol) was added and stirred for 4 hours. The mixture was heated for 2 hours at 60° C., 3 ml of methanol and 0.2 g of C-18 chromatographic phase were added, stirred for 2 hours, filtered, evaporated. The residue was purified using HPLC. Yield: 31-48%.

Example 14: Gram Negative (E. coli and A. baumannii) MIC protocol

Overnight bacterial cultures were grown in LB with no added antibiotics at 37° C. with shaking. A 1:1000 dilution of these cultures into LB was exposed to concentration gradients of compounds in 96-well plates (100 μL per well assay volume). Resulting plates were incubated at 37° C. for 24 h without shaking, and OD600 was measured at the end of the incubation. MICs were determined as the lowest concentrations at which OD600 remained at baseline.

Antibacterial activity of the compounds of the invention is shown in Table 3.

Example 17: Combination Therapies

A serious problem for antibacterial use of tRNA synthetase inhibitors as antibiotics is high frequency of resistance. Recently, Anacor's Anti-LeuS AN3365 failed in clinical trials due to a high frequency of resistance. The problem of resistance may be overcome by employing a combination of molecules targeting different tRNA synthetases in order to decrease the frequency of resistance down to the product of two independent resistance frequencies. E. coli did not develop resistance to a combination of anti-LeuS Tavaborole with our dialkylamine B1 in multiple independent experiments, as shown in FIG. 1. Experimental details: Cultures of E. coli K-12 were started from single colonies on LB-agar plates and were grown in LB for 36 hours with shaking at 37° C. Following that, 10⁸ cells were plated on LB-agar plates containing B1 or Tavaborole alone or in combination adjusted for dose equivalence and incubated at 37° C. for 24 hours.
